Here is variable density print Filaflex running at 75mm/s with the Double Drive Recreus extruder.

The print is a scan of a hand for help fitting a prosthesis. The dense inner is to simulate the bone and a less dense outer to simulate the soft tissue of the skin and muscle. It feels very realistic.
